This implementation is based in Templater actions, created by Jonas Nicklas
other actions like create_file and directory.
Class which holds create directory logic. This is the base class for

The method referenced can be either public or private.

user.rb

return value (should be String) of #file_name:
It calls #file_name from the base and replaces %-string with the

%file_name%.rb

Filenames in the encoded form are converted. If you have a file: 
def convert_encoded_instructions(filename)
  filename.gsub(/%(.*?)%/) do |initial_string|
    method = $1.strip
    base.respond_to?(method, true) ? base.send(method) : initial_string
  end
end

def destination=(destination)


given_destination #=> baz
relative_destination #=> bar/baz
destination #=> dest/bar/baz

end
empty_directory "baz"
inside "bar" do

are related in the following way:
"dest". The destination, given_destination and relative_destination
script is being executed on "dest", it sets the destination root to
It also stores the given and relative destination. Let's suppose our
Sets the absolute destination value from a relative destination value. 
def destination=(destination)
  return unless destination
  @given_destination = convert_encoded_instructions(destination.to_s)
  @destination = ::File.expand_path(@given_destination, base.destination_root)
  @relative_destination = base.relative_to_original_destination_root(@destination)
end

def exists?


Boolean:: true if the file exists, false otherwise.
==== Returns

Checks if the destination file already exists. 
def exists?
  ::File.exist?(destination)
end

def initialize(base, destination, config = {})


config:: give :verbose => false to not log the status.
destination:: Relative path to the destination of this file
source:: Relative path to the source of this file
base:: A Thor::Base instance
==== Parameters

Initializes given the source and destination. 
def initialize(base, destination, config = {})
  @base = base
  @config = {:verbose => true}.merge(config)
  self.destination = destination
end

def invoke! 

def invoke!

    ::FileUtils.mkdir_p(destination)
  end
end

def invoke_with_conflict_check(&block)


conditions are met.
Receives a hash of options and just execute the block if some 
def invoke_with_conflict_check(&block)
  if exists?
    on_conflict_behavior(&block)
  else
    say_status :create, :green
    yield unless pretend?
  end
  destination
end

def on_conflict_behavior


What to do when the destination file already exists. 
def on_conflict_behavior
  say_status :exist, :blue
end

def pretend?


Shortcut for pretend. 
def pretend?
  base.options[:pretend]
end

def revoke! 

def revoke!
  say_status :remove, :red
  ::FileUtils.rm_rf(destination) if !pretend? && exists?
  given_destination
end

def say_status(status, color)


Shortcut to say_status shell method. 
def say_status(status, color)
  base.shell.say_status status, relative_destination, color if config[:verbose]
end
